According to these guys, a factory chain has 10 watts of friction out of the box, 6 watts after being cleaned, and 5.5 watts after being optimized. They use industrial cleaners and laboratory coating applicators to optimize you chain. Price is $76 to optimize your own chain or you can buy one for $99 (DA 9000).
